Technical Field

[0001] The utility model relates to the technical field of slag removal devices, in particular to an earth-rock slag removal device that is convenient for cleaning. Background Technique

[0002] Earth-rock projects generally involve multiple links such as site leveling, foundation pit and trench excavation, roadbed excavation, civil air defense project excavation, floor filling, roadbed filling, and foundation pit backfilling. In these projects, the excavated soil often contains many stone particles. In order to improve the effective utilization of the soil, it is necessary to remove the stone slag in the soil.

[0003] In the existing earth-rock projects, in order to reduce construction costs and follow the principle of not occupying or occupying less farmland and arable land, a reasonable allocation plan for earth-rock needs to be made. When cleaning the stone slag in the soil, if the traditional manual cleaning method is used, not only is the efficiency low, but also the labor intensity is high and the cost is relatively high.

[0004] Although the existing earth-rock slag removal devices have improved the efficiency of slag cleaning to a certain extent, there are still some deficiencies. Some devices may not perform well in dealing with large stone slags, cannot be well broken and screened, and require manual assistance for cleaning, which increases the labor intensity. The cleaning effect of some devices may not be thorough enough, and some stone slags will remain in the sieve plate. Content of the Utility Model

A top cover 4 is clamped on the top of the frame 1, and a feed hopper 5 is fixedly installed inside the center of the top cover 4.

[0026] In an embodiment of the present utility model, a crushing assembly 6 is provided on the frame 1. The crushing assembly 6 includes a U-shaped frame 61. The U-shaped frame 61 is fixedly installed on the outer wall of the top end at the rear side of the frame 1. A servo motor 62 is fixedly installed inside the U-shaped frame 61. A crushing roller 63 is fixedly installed on the output shaft of the servo motor 62. There are two groups of crushing rollers 63. The crushing rollers 63 are rotatably installed inside the frame 1. In addition, the feed hopper 5 is located directly above the two groups of crushing rollers 63. A driving gear 64 is fixedly installed on the outer side of the crushing roller 63 at one end of the frame 1. A driven gear 65 is fixedly installed on the outer side of the crushing roller 63 at the other end of the frame 1. The driving gear 64 meshes with the driven gear 65. When the servo motor 62 on the U-shaped frame 61 is started, the two groups of crushing rollers 63 rotate towards each other by cooperating with the driving gear 64 and the driven gear 65, so as to crush the materials input into the frame 1 from the feed hopper 5. A round rod 66 is fixedly installed inside the frame 1. An inclined plate 67 is hingedly installed on the outer side of the round rod 66. A hinge seat 68 is fixedly installed inside the inclined plate 67. In addition, there are two groups of the inclined plate 67 and the hinge seat 68. Both groups of the inclined plate 67 and the hinge seat 68 are mirror-symmetrically arranged at the left and right ends of the round rod 66 with the horizontal midline in the front and rear direction of the round rod 66 as the mirror axis.

At the same time, when the servo hydraulic rod 69 is started, the round rod 66 and the hinge seat 68 are cooperated to make the two groups of inclined plates 67 swing back and forth, so that the crushed material can be received, thereby avoiding damage to subsequent parts. Finally, with the screen plate 610 and the discharge port 611, screening can be conveniently performed, and the material with small particle size enters the fine material box 2, and the material with large particle size enters the coarse material box 3, and then the earth and stone can be removed more conveniently. Furthermore, when the servo hydraulic cylinder 71 is started, the L-shaped rod 72 can reciprocate, thereby driving the screen plate 610 to reciprocate inside the frame 1, so that the crushed material can be better discharged and screened, avoiding accumulation that causes inconvenience in cleaning, and then the removal efficiency can be better improved.
